  1. Automated Web Patrol with Strider HoneyMonkeys:Finding Web Sites That Exploit Browser Vulnerabilities Y.-M. Wang, D. Beck, X. Jiang in Proceedings of the 13th Annual Network and Distributed Systems Security Symposium (NDSS 2006), The Internet Society, 2006. Presenter: Sangyup Lee

  2. Summary • Introduces the concept of Automated Web Patrol • Basic aim is at protecting Internet users • Design and Implementation of the system • Effectiveness of the system is demonstrated through a series of experiments

  3. What is the Strider HoneyMonkey Exploit Detection System? • A pipeline of VM-based honeypots that run monkey programs which patrols the web automatically in an attempt to mimic human web browsing. • Honeypot • A trap to catch malice • Records attacker’s information

  4. What is the Strider HoneyMonkey Exploit Detection System? (contd.) • Pipeline • Consists of 3 stages Stage 1: Exploit Site Detection on un-patched VMs Stage 2: Recursive Redirection Analysis on un-patched VMs Stage 3: Recursive Redirection Analysis with partially and fully patched VMs • Exploit detection by detecting persistent-state changes

  5. Appreciative Comment • A good way of approaching the solution to the growing problem of browser-based attacks • Concept of prevention • Possible developments in future

  6. Critical Comments #1 • Only one type of web browser used in the experiments – Internet Explorer 6.0 • Should have taken into account other popular browsers such as Firefox

  7. Critical Comments #2 “…to seek out and classify web sites that exploit browser vulnerabilities.” • Ambiguous use of different Windows XP Service Pack versions on the tested machines. • Is it the OS or the browser that’s vulnerable? • Other factors that might affect the vulnerability?

  8. Further Analysis “if I never visit those risky web sites that serve dangerous or questionable content, do I have to worry about vulnerability exploits?” “They don’t buy it because the danger is small and because security is a pain.” – B. Lampson

  9. Discussion • Can you think of any other factors that might affect the vulnerability of your machine against browser-based attacks?
